??? I've never heard of a floating check valve in a black (or grey) tank vent. I can see no reason for a manufacturer to install one; The only way to "overfill" the black tank is with the rinser, and in that case, it would be better to have the overflow go out onto the roof rather than overpressurizing and dropping (like yours did) or even splitting the black tank open, or flowing out through the toilet (or bathroom sink if plumbed that way). Sounds like a made-up excuse by the dealer. :S
Have that dealer show you that floating check valve. In 40 years working on RV's and dropping countless tanks, I have NEVER seen anything inside a tank or connected to a Vent system in or around the tank. Every week, I think I cannot find something new that a Dealer/Tech/ customer posts that is BS. Well, this makes my week:B Doug
